STORAGE BATTERY.

Specification of Letters Patent.

Patented Aug. 13, 1907.

Application filed April 16, 1906. Serial No. 311,928.

T 0 all whom it may concern:

Be it known that 1, CHARLES Bauer, a citizen of the United States, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented a certain new and useful Improvement in Storage Batteries, of which the following is a full, clear, and exact description, referencebeing had to the accompanying drawing, which forms a part of my specification.

My invention relates to electric storage batteries, of the character, for example, of those generally adaptable for use in fire and police alarm systems.

The object of my invention is to provide a storage battery provided with a top so formed as to prevent the escape of the gases and the bubbling over of the liquid during the process of charging the battery, and

v the formation ofthe coating on the outside of the upper tion, and may be used with any batteries of the type referred to.

In the drawingss-Figure 1 is a side elevation of a battery with my improvement attached, a part of the wall of the body being broken away at the upper edge to more clearly illustrate the top; Fig. 2 is a side eleva' tion of the top; Fig. 3 is a plan view of the top looked at from below; and Fig. 4 is a section through Fig. 2 on the line H thereof.

A is the cell, B, B, the elements, and C the top of the battery. It will be understood of course, that these cells are arranged in series in the usual manner, with the positive element of one battery connected to the negative element of the next battery. This feature of the apparatus is as usualand forms no part of, my invention.

The top C is of sufiiciont extent to have its edges projecting beyond the top of the cell, the top thus having formed on the four sides an overlapping flange (1. Below this flange the top extends vertically for a short distance with its four edges in contact with the inner walls of the cell, as seen at c. It is then curvedinward and downward away from the our planes oi the inner walls of the cell, so as to form a depending (-urvcd flange, said flange having concave, curved sides D terminating in a more or less rounded edge 11, and also concave, curved ends D. Openings E are formed at each side of the top to permit of the extension through the top of the supporting ends of the elements.

From the description it will be apparent that when the cell is charged, and there occurs the resultant bubbling up of the liquid contained in the cell, the hubbling and upwardly spurting liquid will be caught on the concave sides and ends of the flange, depending from the top. The vapor will be condensed, and when condensed it, with such other liquid as by the violence of the bubbling has been carried up, will gradually travel along the concave sides of the flange down to the edge d thereof, and when sufficient has collected thereon, will drop back into the main body of the battery.

The advantages of my invention are apparent from the description.

Having thus described my invention, what I desire to claim as new and to cover by Letters Patent, is:-

1. In a storage battery, in combination with the cell, a top therefor having a flange resting upon and projecting beyond the upper edges of said cell, said top being provided with a depending flange having concave, curved sides and ends terminating in an edge extending in the direction of the length of the top.

2. In a storage battery, in combination with the cell, a top having a flange portion adapted torest upon the upper edges of said cell, a vertical portlon adapted to engage the inner walls of the upper edges of said cell, and a depending flange having concave. curved sides and ends terminat- 8O ing in an edge extending in the direction of the length 01! said top.
